Jenni Glover & Anor v Fluid Structural Engineers & Technical Designers Limited & Ors

The main application before the court is the claimants’ application, issued on 25 April 2024, seeking permission for a new structural engineering expert in place of Mr Andrew Hardy together with consequential directions.

The sixth defendant (“AXA XL”) by its application issued on 23 February 2024 seeks the revocation of the claimants’ permission to rely on the evidence of Mr Hardy. This application is, effectively, conceded.

Against a background of the Claimants’ admitted interference in the expert process, AXA XL resists the appointment of a replacement expert alternatively submits that any permission should be conditional on extensive disclosure of without prejudice communications with Mr Hardy. By the time of the hearing the claimants had identified Richard Tant of Richard Tant Associates as the replacement expert they wished to retain.

The third matter before the court concerns an earlier application by the claimants issued 16 February 2024 seeking an extension of time for service of a Schedule of Loss. The costs of that application remained to be determined however it was apparent from the parties’ skeleton arguments before me that the parties are now in agreement as to the appropriate costs order.

The applications occupied a full day on Friday 3 May 2024. Given the timetabling issues that arose, I told the parties that I would provide my decision after the Bank Holiday Monday with full reasons to follow. On Wednesday 8 May I made the order set out at the end of this judgment. This judgment contains the reasons for that order.

The claimants are the owners of 124 Westbourne Grove, London, W11 2RR. It is not in issue that in around 2016 they commenced renovation works including the creation of a new basement. Whilst carrying out these works damage was suffered to surrounding properties including 122 Westbourne Grove (“the adjoining owners”).

By its Particulars of Claim dated 4 July 2022 the claimants brought claims against a number of parties including Chase Construction (Contracts) Limited, the original building contractor for the works and Fluid Structural Engineers & Technical Designers Limited the appointed structural engineers for the works. I am advised that the other claims have been compromised and the claimants now only proceed against AXA XL.

The claimants updated schedule of loss dated 1 March 2024 identifies a VAT inclusive sum of £1,881,005.61 in respect of damage to 122 Westbourne Grove.

The claimants seek a declaration that they are entitled to an indemnity from AXA XL under an insurance policy issued in their favour. By its defence dated 26 August 2022, AXA XL seeks to rely on what it contends are an extensive range of exclusions in the XL policy excluding liability for damage that (i) was the fault of the builder or designer, (ii) was inevitable damage, (iii) was recorded in a survey attached to the policy or (iv) was due to works undertaken prior to the start of the policy. It can therefore be seen that issues as to the cause, nature and extent of damage and when it occurred are central issues between the parties.

The trial is listed to commence on 16 September 2024 with a reading day, 5 days of evidence with oral closing submissions to follow on 26 September 2024.

On 22 March 2024 a party wall award was issued in relation to a dispute between the claimants and adjoining owners. This found the sum of £1,832,638.76 as payable by the claimants to the adjoining owners. That award is the subject of an appeal dated 3 April 2024.

At the costs and case management conference on 4 April 2023 HHJ Stephen Davies gave permission to the parties to call expert witnesses in respect of structural engineering and quantum. That evidence was timetabled in the usual way to rule 35.12(3) statements followed by experts’ reports.

The claimants engaged Mr Hardy as their structural engineering expert. AXA XL engaged Mr Howard Tucker.

The Rule 35.12(3) statement evolved through various drafts reflecting discussions between the experts. When the draft was at an advanced stage Mr Tucker expressed his concern to RPC, solicitors for AXA XL, as to what he believed to be significant changes to Mr Hardy’s views recorded in the latest version. Put shortly, Mr Tucker was concerned that on the face of it there appeared to have been involvement from the claimants’ lawyers.

A joint statement was nevertheless agreed and signed on 3 November 2023.

By letter dated 12 December 2023 RPC wrote to Pennington Manches Cooper (“PMC”), solicitors for the claimants addressing complaints made by PMC as to delays in finalising the experts’ joint statement:

In its letter of 14 December 2023 PMC addressed a number of matters. On the issue of interference in the Joint Statement process it stated :

In a brief response on 21 December 2023, RPC stated :

That letter of 21 December 2023 did not receive a response until PMC’s letter 16 January 2024, the material parts of which are set out below:

Perhaps understandably, that response did not satisfy RPC who responded on 24 January 2024. This was a lengthy letter, extracts of which I set out below :

The letter of 24 January 2024 also addressed paragraph 13.6.3 of the TCC Guide. It observed that the Civil Justice Council’s guidance was directed to settling the agenda for experts meetings whereas the particular concern of AXA XL concerned the changes between revisions 3 and 4 of the EJS. In that regard, reference was also made to BDW Trading Ltd v. Integral Geotechnique (Wales) Ltd [2018] EWHC 1915 (TCC) highlighting the following in paragraph 18 of the Judgment of HHJ Stephen Davies :

RPC continued later in the letter of 24 January 2024:

As set out above, on 23 February 2024 AXA XL issued an application seeking the revocation of the claimants’ permission to rely on the evidence of Mr Hardy.

In its letter of 14 March 2024 referring to the application PMC stated :

The final letter relevant in this exchange to which I need to refer is from RPC dated 21 March 2024. That letter noted that the statement made in PMC’s letter of 16 January 2024 that its approach to giving directions to experts in any litigated case was entirely in line with paragraph 13.6.3 of the TCC Guide and section 75 of the Civil Justice Council’s guidance on experts was not true. RPC observed it was disappointing that it required an application to the court for the true position to be acknowledged. In addressing the proposals made:

In her statement of 23 February 2024 Ms O’Callaghan of RPC exhibited and commented on the correspondence set out above.

Peter Stockill, the partner at PMC with overall supervision of the claimants’ claim, provided a statement dated 25 April 2024 in support of the claimants’ application. Privilege was waived in relation to communications between PMC and Mr Hardy as exhibited to his statement. This included the drafts of the experts’ joint statement.

In addressing the expert process, Mr Stockill states :

Give that admission it is unnecessary to go through the totality of the communications with Mr Hardy on drafts 2, 6 and 7 in respect of which privilege was waived. The stated intention underlying the revisions to the third draft statement is apparent from an email dated 12 October 2023 and sent to Mr Hardy by an associate at PMC, copied to Mr Stockill:

There were extensive revisions and deletions made to the third draft. To fully understand their nature it is necessary to compare the third draft enclosed to the e-mail of 11 October 2023 with that provided to PMC by Mr Hardy on 9 October 2023. The revisions were generally undertaken by way of track changes with explanations provided by way of “Commented” boxes adjacent to the revised text.

At paragraph 50 of his witness statement Mr Stockill addresses the revisions made. Given Mr Stockill does not seek to justify the revisions made it is unnecessary to address them in great detail however I indicate their nature below by way of examples below.

Issue 1.2 “Expectation of damage” was revised to read “Inevitability of damage”. The previous wording against that issue:

In his witness statement Mr Stockill explained that the revised wording was to refer explicitly to the policy exclusion wording in circumstances where the earlier draft used terms which were “unhelpful” because the policy wording was “inevitable” and that addressing issues such as “Expectation of damage” and “Accepted limits on damage to neighbouring properties” (the wording in issues 1.2 (second) and 1.3 which was similarly revised) may “lead the experts to answering the wrong question”.

Against Issue 3.2, “Grout gap between party wall underpinning and the executed work face” the previous wording under “Statement” was recorded as “Agreed” by Mr Hardy and Mr Tucker:

Mr Stockill seeks to explain this revision as follows:

Issue 4.1 “Cause of damage” was revised to add the underlined words:

Mr Stockill explains that addition to the Statement column on the basis that Issue 4.1 “did not address the specific insured perils in the insuring clause (collapse subsidence etc) so we added these for the experts to consider”.

The revisions ultimately made were then passed by Mr Hardy to Mr Tucker in a draft 4 dated 12 October 2023. I make clear that not all of these revisions found their way into the later draft or the final version of the joint statement agreed on 3 November 2023 although some did (such as the revision to Issue 1.2 and 4.1 (including the typographical error).

Paragraph 13.6.3 of the TCC Guide, to which reference has already been made, states:

In Imperial Chemical Industries Ltd v. Merrit Merrall Technology Ltd [2018] EWHC 1577 (TCC) at [237] Fraser J (as he then was) stated:

Before me there is no disagreement between the parties as to these principles or their application. The wording of paragraph 13.6.3 is clear. Nevertheless, Mr Stockill’s evidence is that there had been a failure to understand the applicable rules and guidance for which he apologised unreservedly to both the court and AXA XL.

What is clear from the correspondence is that PMC believed it was permissible to amend the draft statement where it was thought the content did not reflect the pleaded issues and said the same to RPC (see for example, paragraph 8 of the letter of 16 January 2004). Such a belief, however misguided, is not the same as a deliberate and knowing disregard of the applicable principles.

Mr Stockill further states that whilst in acting as it did PMC did not intend to have any impact on the substance of the views of Mr Hardy or his independence, he accepts the Court could not now be satisfied as to Mr Hardy’s independence. On the evidence before the court it is clear that it cannot be satisfied as to the independence of Mr Hardy in the joint statement process, however I should make clear that I have no evidence before me from Mr Hardy himself.

The deletion of metadata is explained as occurring under time pressure in circumstances where the wish was not to share comments with others. In particular the identification that text had been added at the suggestion of PMC was sought to be avoided. In so doing, Mr Stockhill makes clear this is neither his common practice nor that of the associate who wrote the e-mail of 12 October 2023 and neither can recall ever having done so before. Nevertheless such conduct was thought at the time to be justified as the comments were regarded as privileged in any event. As Mr Stockill states in his witness statement “We also did not wish to be conspicuous about our involvement because we did not want to turn the joint statement process in a lawyer led process.”

It must be observed that the actions taken had precisely (and predictably) the very consequence Mr Stockill was striving to avoid. The revisions made caused Mr Tucker to be understandably concerned as to the joint statement process. The consequence of this was the involvement of the parties’ legal representatives addressing the joint statement process leading to the current applications before the court.

What divides the parties are the circumstances in which permission should be given for a replacement expert and the conditions to be attached to any such permission. In addressing these issues a number of authorities were cited, most were directed to the conditions to be attached to any permission to change experts. I address them chronologically.

In Edwards-Tubb v. JD Wetherspoon plc [2011] EWCA Civ. 136 the Court of Appeal imposed conditions on a claimant who wished to change expert from the expert originally retained for the purposes of the pre-action protocol for personal injury claims. Having first concluded that there was no difference between a change in expert pre-issue (as part of the pre-action protocol procedure of co-operation) and post-issue, Hughes LJ stated, at paragraph 31 :

In that case the reason for the change of expert was not clear and as the Court of Appeal noted it was not permissible to infer at trial that the earlier report was unfavourable to the claimant if the claim for privilege in the earlier report was successful.

As I have observed the claimants have already waived privilege in respect of such of the joint statement process as the claimants’ consider necessary to deal with the applications.

In Adams v. Allen & Overy and Others [2013] EWHC 4735 (Ch) the claimants’ allocation questionnaire identified an expert different from the chartered surveyor originally retained. As part of the pre-action process, that earlier expert, Mr Smith, had also prepared a “second and rebuttal commentary.” In the defence of the second and third defendants Mr Smith was expressly referred to and his evidence described as “fatally flawed”. Mr Smith subsequently declined to act with the necessity for the claimants to retain a new expert.

In that case there was no evidence that the expert’s unwillingness to continue was anything other than genuine and in particular, it was not a mask for some ulterior reason on the part of the claimants’ legal team to be rid of him as an expert. Against that background, Foskett J considered whether there was anything else that Mr Smith or the claimants’ legal team should convey to the defendants’ legal teams as a condition of granting permission. As the Court observed, the reports had already “been revealed”. At paragraph 49 the court concluded:

In Murray v. Devenish [2017] EWCA Civ. 1016 the Court of Appeal was considering a case where the claimant appellant, or more particularly its counsel, had lost confidence in the retained expert. At first instance the Judge refused permission to change experts having regard to the proximity of the trial date and the claimant’s previous conduct of the proceedings. In the event, once permission to appeal was granted, the claim was stayed and the trial date vacated until determination of the appeal.

Having concluded that he would not have interfered with the case management decision made by the Judge at first instance as it was a decision he was entitled to reach, Gross L.J. noted that the position before the Court of Appeal was different in that there was no new trial date. In those circumstances, whilst dismissing the appeal, the Court of Appeal gave permission for the replacement expert subject to disclosure of previous reports.

In reaching the same conclusion Underhill L.J. did not regard this as a case of expert shopping in the pejorative sense and whilst stating that he would not necessarily have reached the same conclusion as the court at first instance, it could not be said that the decision was not open to him.

The decision of HHJ Stephen Davies in B.D.W. Trading Ltd has been referred to above. In that case it became apparent during the evidence given at trial that the defendant’s expert had made changes to the first draft of the Joint Statement as a result of comments and feedback received from the defendant’s solicitors.

Against that background HHJ Stephen Davies concludes:

In the Dana UK Axle Ltd v. Freudenberg FST GmbH [2021] EWHC 1413 (TCC) an application was made on Day 7 of the hearing to exclude the defendant’s technical expert evidence. The basis of the application was the discovery of numerous breaches by the defendant’s three experts of CPR Part 35 and the 2014 Guidance for the Instruction of Experts in Civil Claims. These breaches were particularly concerning given that in granting relief from sanction for the late service of the defendant’s three technical expert reports, O’Farrell J imposed conditions. These conditions comprised the provision of full details of all materials provided to those experts by the defendant’s solicitors and the defendant itself, disclosing all documents produced by or provided to each experts during any site visit (including notes taken) and identifying the source and details of the data and other information relied on in support of each proposition/opinion. Those conditions were, in the event, not complied with.

Having established the extent of the non-compliance Joanna Smith J refused permission to rely on the technical expert reports in circumstances where the defendant’s failures to meet the conditions imposed by the PTR Order meant it did not have permission. It is clear from the judgement that the court considered there was a lack of candour in the responses to earlier enquiries directed to the conditions and the extent to which they had been complied with. In her concluding paragraph Joanna Smith J states :

In Rogerson v. ECO Top Heat Power Ltd [2021] EWHC 1807 (TCC) Mr Alexander Nissen QC, sitting as a Judge of the High Court provided a helpful review of the authorities on changing experts and the imposition of conditions. In that case he concluded that the defendant was seeking to call a different expert “for a reason which I infer to be or at least has the appearance of expert shopping”. As a result, when giving permission to change experts he imposed wide-ranging conditions of disclosure extending to reports, letters and attendance notes from the previous expert to the defendant, its solicitors and others and attendance notes by the defendant’s solicitors setting out or referring to the expert’s views on causation.

Patricia Andrews v. Kronospan Ltd [2022] EWHC 479 was a case where the claimant’s solicitors had commented on drafts of an expert joint statement provided to them by the claimant’s retained expert for the purpose of soliciting their assistance. Senior Master Fontaine concluded that the expert’s approach and acted in a way which “strongly suggests he regarded himself as an advocate for the Claimants, rather than as an independent expert whose primary obligation is to the court” (paragraph 31 of judgment refers).

As in the present case, the Court had no evidence from the expert as to the reasons for his conduct (whether he was unaware of his obligations as an expert and if so, why, or whether he was aware, in which his case his reasons why he thought it was appropriate to transgress those obligations).

Having found that she had no confidence in the expert’s ability to act in accordance with his obligations as an expert witness the claimants’ permission to rely on his evidence was revoked. In granting permission for a replacement expert and applying the overriding objective Senior Master Fontaine noted that the trial date was not in jeopardy because no trial date had been set. Account was also taken of the fact that the claim was one in nuisance where the claimants would, if successful, seek an injunction or declaration as well as damages so they would not be fully compensated by a claim against their solicitors (paragraph 35 refers).

In The University of Manchester v. John McAslan & Partners Ltd and Others [2022] EWHC 2750 (TCC) Mr Roger ter Haar KC sitting as a Deputy High Court Judge provides an extensive and helpful review of the authorities on conditions to be attached when granting permission to change experts. In noting the judgment of Stuart-Smith J in Vilca v. Xstrata Ltd [2017] EWHC 1582 (QB) he sets out at paragraphs 26 and 27 addressing those situations where there is a power to impose conditions (the emphasis is added by Mr ter Haar KC):

In that case the court concluded that the interests of the defendants were sufficiently protected by the disclosure already given. In The University of Manchester there had been a change of position and the claimant did not wish to call evidence from the experts sought to be replaced. The court concluded that the courts discretion to impose conditions was engaged:

The final authority to which I was referred is the decision of O’Farrell J in Avantage (Cheshire) Ltd and Others v. GB Building Solutions Ltd (in administration) and Others [2023] EWHC 802 (TCC). That case concerned an application to call a new expert, Dr Neil Ketchell, in place of a forensic scientist and a fire engineer. The necessity to replace the forensic scientist was due to her serious illness which prevented her participation in the proceedings. Whilst concerns were raised as to the reasons for replacing the fire engineer with suggestions of expert shopping, permission was given when it became clear that the claimants were not happy with their original expert and wanted to have permission to rely on an expert in whom they had confidence. The detail of that lack in confidence was not before the court however it was accepted that this would be apparent should disclosure of the experts’ reports be made a condition of granting permission to change experts. Such a condition was imposed however the court refused the application to disclose attendance notes of discussions with that expert:

In the claimants’ written note, Mr David Turner KC and Mr Luke Wygas identify seven factors which they submit are relevant to the determination of whether permission should be granted to replace an expert and if so, subject to what conditions:

Mr Rónán Hanna appears for AXA XL. Given there is now no longer an issue as to the revocation of permission for Mr Hardy to give structural engineering evidence, his submissions focussed on the consequences of that revocation. Permission for a replacement expert was resisted on the basis of the application as presently formulated. In essence, AXA XL submits that any permission should be conditional on further extensive disclosure. In support of this Mr Hanna submits that there was covert interference by PMC with Mr Hardy’s evidence and the effect of this was to alter the views expressed which included deleting wording in which Mr Hardy was recorded as agreeing with key parts of the case advanced by AXA XL.

Mr Hanna does not suggest that new structural engineering evidence cannot be accommodated in time for the September hearing. However he notes, with some force, that it would have been helpful to have at least a draft of the proposed report before the court. On that point, I am told by Mr Turner that there was no contact with Mr Tant prior to PMC’s letter of 14 March 2024 in which it sought agreement to revoke the claimants’ permission to rely on expert evidence from Mr Hardy. Whatever the reason, there is no draft report before the court.

AXA XL believes it has a complete defence under the terms of the policy and it is understandably keen that the liability hearing proceeds in September this year. Greater concerns are expressed in relation to quantum. Given it is accepted there needs to be an updating of the Schedule of Loss to which AXA XL in turn needs to respond, Mr Hanna submits it is unrealistic to consider quantum can be dealt with in the original trial window. He also identifies the impact of the appeal as a good reason why, in his submission, quantum should be deferred until after determination of the appeal.

I deal first with the question of permission for a replacement expert. I do so on the basis that the facts set out above disclose substantial and impermissible interference in the expert statement process by those acting for the claimants. Such interference is clearly contrary to both authority and the applicable guidance issued by the TCC.

When considering the question of a replacement expert I have regard to the overriding objective of enabling the court to deal with cases justly and at a proportionate cost. This includes dealing with cases in ways which are proportionate to the amount of money involved, ensuring a case is dealt with expeditiously and fairly allocating an appropriate share of the court’s resources and enforcing compliance with rules, practice directions and orders.

I accept Mr Hanna’s submission that there is no reported decision on all fours with this case. Every decision is fact sensitive and whilst there can be no excuse for the conduct of the claimant’s solicitors, justice is best served by maintaining the trial date if at all possible and ensuring that AXA XL has sufficient disclosure to understand Mr Hardy’s views, however unlikely it is that AXA XL would wish to deploy his report as evidence at trial pursuant to the provisions of CPR part 35.11.

In that regard, if the consequence of a replacement structural engineering expert had been to lose the trial date this September then, for that reason alone, I would not grant permission. However as I discuss below, that is not the case here and perhaps understandably the claimants have provided revised directions for the structural engineering evidence which keep the trial date.

I consider permission should be given for Mr Tant to be an expert witness in the field of structural engineering. My reasons for doing so are:

Mr Turner also observes that any claim against PMC would not be straightforward in that it would be in essence a claim for a “loss of a chance”. I accept this and that such a claim would take up further Court resources however on its own I do not consider this a sufficient reason to grant permission. It is not unusual for the conduct of legal representatives to result in serious sanction against their client, yet no authority has been cited which suggests that this is a material consideration militating against the imposition of a sanction that would otherwise be justified. It can be a relevant factor for consideration, as in Patricia Andrews and ors where the relief sought included an injunction or declaration as well as damages so that the claimant would not be fully compensated by a claim against their solicitors.

As noted above, in addressing the applications there has been a significant waiver of privilege by the claimants. This extends to the draft joint statements and the comments of PMC on the same. AXA XL seeks further disclosure beyond this. In his oral submissions Mr Hanna confirmed this was limited to attendance notes and e-mail correspondence with Mr Hardy (suitably redacted to remove reference to other matters outside the scope of his evidence).

To the extent necessary to decide, I do not consider this is case of “expert shopping” in any pejorative sense. As I have observed, it is Mr Stockill’s evidence that he considers Mr Hardy supports the claimants’ pleaded case and that the proposal to replace him was not made lightly given his extensive knowledge having been involved for almost 5 years. Rather it was made to provide a fair and swift resolution of any concerns of non-compliance and the independence of Mr Hardy’s evidence. I accept that is Mr Stockill’s view. In any event, I consider that the extent of disclosure given, in addition to Mr Hardy’s report, meets the concern to ensure that full information is available to the claimants consistent with the authorities to which I have already referred. I am not persuaded that the further disclosure sought is necessary. In particular, even assuming there has been a material change in Mr Hardy’s support of the claimants’ case (which has not been demonstrated), I do not accept that the views expressed by Mr Hardy in the draft joint statements prior to revision cannot be taken to be his true objective views. Further, such additional disclosure has the potential for difficulty identified by O’Farrell J in Avantage.

Whilst AXA XL did not wish to lose the trial date for a hearing on liability, Mr Hanna submitted that it was now too late to hear quantum in September 2024. The current position is that by order made on 10 April 2024, HHJ Stephen Davies extended the date for the quantum joint statement (from 10 May 2024) to a date to be fixed at the current hearing which was listed as expedited.

As to the state of quantum, Mr Wygas helpfully took me through the pleadings and the Schedule of Loss. On analysis, the position is not complicated and the necessary changes are not significant. By reference to AXA XL’s response to the Scott Schedule of Damage and Repairs dated 12 May 2023 it can be seen that the detail of the works to the adjoining owner is set out at item 3 onwards. That detail can be found reflected in the Updated Schedule of Loss dated 1 March 2024. That Updated Schedule of Loss pleads a figure of £1,881,005.51 inclusive of VAT. This can be compared with the sum of £1,832,638.76 detailed in the award of 22 March 2024

It is perfectly possible to timetable the necessary changes to quantum and provide directions for joint statements and reports in advance of the hearing in September 2024. Whilst the order of 10 April 2024 did not formally stay the remaining steps in quantum, even if matters are timetabled starting from the date of receipt of my Order the extended dates I have directed for the quantum joint statement and reports slightly extend the periods originally granted, preserve the trial date and ensure all evidence is served prior to the pre-trial review listed for 19 July 2024.

This brings me to the issue of the party wall appeal. The parties are proceeding on the basis that the result of the appeal is going to be relevant to the claimants’ loss in respect of no 122 Westbourne Grove although they do not agree as to the extent of the overlap between the appeal and the issues in the present proceedings. This has not been explored in any detail before me although I note that the similarity between the award and the sum claimed against AXA XL may suggest that the overlap is somewhat greater than contended for by Mr Hanna.

The present position is that the appeal before the county court is subject to a two month stay for ADR. The stay was agreed at the claimants’ request and was ordered on 15 April 2024. The directions given by the county court consequential on the stay included a case management conference on the first open date after 13 August 2024 but no later than 3 September 2024. I have no evidence as to the state of any settlement discussions but if the appeal proceeds I am told by counsel that any hearing is likely to be almost a year away.

As already observed, in support of his submission to adjourn quantum, Mr Hanna relies on the uncertainty of quantum prior to the resolution of the appeal.

Mr Turner makes a similar point noting that under section 10(16) of the Party Wall etc. 1996 Act (“the Act”):

Mr Turner relies on this uncertainty to submit that the best way forward is for the appeal and these proceedings to be heard together. To facilitate this he suggests that a case management conference be listed in both cases assuming that the county court can be persuaded to make an order that the appeal be managed and heard by a judge of the TCC and if so, that the TCC judge can sit as a County Court Judge (as provided for under Section 5(2) of the County Courts Act 1984). I understand that this would likely extend the time estimate due to the involvement of the adjoining owners and the need to address the appeal.

I reject that approach. It would have the effect of adjourning the hearing in these proceedings for over a year to July 2025 if HHJ Davies remained as the trial Judge. As paragraph 7.4 of PD29 makes clear, the court will not allow a failure to comply with directions to lead to the postponement of the trial unless the circumstances are exceptional…and that if it is practical, to do so, the court will exercise its powers in a manner that enables the case to come on for trial on the date or within the period previously set. The adjournment of the trial is not a conclusion to which I am driven. AXA XL wishes to keep the hearing date, at least for liability.

I have no evidence before me as to the wishes of the adjoining owners. I understand they have not been asked whether they agree to the appeal being heard at the same time as these proceedings. Further, whilst no argument has been directed to the proper construction of the Act and its conclusiveness provisions, I do not consider that the course of these proceedings should be dictated by the course of other proceedings:

It follows that I do not consider either liability or quantum should be adjourned to a later date. If the position in respect of the party wall appeal becomes clearer then the parties can always revisit the position however this observation is not to be taken as encouraging the same. In the meantime the parties should prepare for the hearing in September in accordance with the terms of the order previously communicated to the parties and set out at the end of this judgment.

The costs consequences of the grant of permission for a replacement expert are largely agreed. When considering the appropriate costs order to reflect the additional costs caused by the engagement of a new structural engineering expert at this late stage I have been guided by the approach of Foskett J in Adams. I recognise that there may well be material in Mr Tant’s report which it would have been necessary to consider in any event and so, as in Adams, “I do not think it is as simple as simply paying the sums said…to have been expended in considering and answering [the new report] ” (paragraph 48 of the judgment refers). On the limited information before me, in addition to paying the costs thrown away as a consequence of the permission for Mr Tant, I consider that the appropriate order is that claimants shall also pay 30% of the costs of the AXA XL considering the structural engineering joint statement and expert report of Mr Tant.

It follows that for the reasons set out above I order:
